Currently, I am working on a project using single spa and I need to implement a loader while my micro app is being loaded. Additionally, I also need the loader to be displayed when switching between these micro apps. Are there any methods to accomplish this task?
Check out the following link for more information on utilizing single-spa-layout:
import { registerApplication } from 'single-spa';
registerApplication({
name: "app1",
app: loadApp1,
activeWhen: '/'
})
function loadApp1() {
return Promise.resolve().then(() => {
placeLoader()
return System.import('app1')
}).then(app => {
removeLoader()
return app;
})
}
function placeLoader() {
document.body.appendChild(
Object.assign(document.createElement('img'), {
id: 'single-spa-loader',
src: "loading.gif"
})
})
}
function removeLoader() {
document.getElementById('single-spa-loader').remove()
}
